James Bissell-thriller opening

The sequence starts in a pitch black room with just a women's voice being heard as she cries for help. Suddenly the lights come on in the room revealing the girl sat on the floor handcuft to the leg of one of the table legs. All of a sudden a deep mysterious voice is heard from a set of speakers that are in the room telling her the only way out is to find the key to uncuff herself, however if she doesn't find the key within five minutes the lights will go out again and she will be left in the dark to die. The kidnapper also tells also tells the girl that in her right pocket is a key but this key doesn't fit the handcuffs. The girls' five minutes begin and she staggers around the room as far as she can in order to find the key. The cut pace will be much quicker here to enphasise the tension in this scene. Eventually the girl finds the key under a table with ten seconds to spare before releasing the cuffs. The mysterious voice then comes over the speakers again telling the girl that the door to the room may not be as harmless as it looks and that the key in her pocket will open the door but whether she chooses to do so is up to her.....
